Housed in a round 31 mm case crafted from 18 kt yellow gold, this Datejust 31 features the Oyster architecture: a monobloc middle case, solid screw-down case back, and a screw-down winding crown with Twinlock double waterproofness, delivering water resistance to 100 metres. The fluted bezel frames a scratch-resistant sapphire crystal fitted with a Cyclops lens over the date window.
The dark grey dial is set with diamonds in 18 kt gold settings, while the President bracelet — rendered in 18 kt yellow gold with semi-circular three-piece links — fastens via a concealed folding Crownclasp. Together, the dial and bracelet create a cohesive presence defined by warm gold tones and diamond brilliance.
Power comes from Calibre 2236, a perpetual mechanical self-winding movement manufactured by Rolex. It runs on a bidirectional Perpetual rotor, incorporates a Syloxi silicon hairspring with patented geometry and Paraflex shock absorbers, offers a power reserve of approximately 55 hours, and achieves COSC-certified precision of -2/+2 seconds per day after casing. Functions include centre hour, minute and seconds hands, an instantaneous date with rapid setting, and stop-seconds for precise time adjustment.
